With surprisingly little fanfare, Apple has embraced a new user interface. When you pay with Apple Watch, you will both hear and “feel” a confirmation. A “gentle tap” on the device can be sent to another Watch wearer, who will feel the touch on their wrist. Is this a reminder? A nag? Longing? Answer: this is an entirely new form of human-to-human communications. It’s no surprise that Apple Watch “taps” can be customized for different people and different interactions.
I'd love to get terribly excited about the Apple Watch's haptic, or as it will come to be known post launch, Taptic feedback, but then I remember this is a first generation product with barely room for a MEMS (micro-electro-mechanical system) type acutator good for a buzz or variations there of. Not that it won't be useful (can we bring this to iOS keyboards?), or even entertaining, but like all new tech its real potential is hard to guess from here.
